Red Hat Gluster Storage is a combination of the GlusterFS network file system, which aggregates storage on commodity hardware over Ethernet or Infiniband, and the Ceph-based Inktank Storage from the eponymously named company. Red Hat bought Gluster in 2011 and Inktank in 2014.

Canonical claims Ubuntu – also on Google’s Cloud - runs 70 per cent of Docker images on AWS and 80 per cent of OpenStack.

Red Hat jumped on the Google cloud train in November 2013, joining as a certified partner. Since then it has hefted RHEL, Atomic Host and OpenShift onto Compute Engine and made Red Hat Cloud Access available in selected Red Hat subscriptions. ®
